I have finally put together some kind of metal material that looks about right for this type of collar/cuff, I did a quick bake test (second picture) and it appears to hold “relatively” well. I have added a scratch layer that shows through with a wear map, and some coloration variations in an effort to make the welds more visible.

Today’s update also include two random things. (I saw a latex pig mask in a fetish photo that I thought actually looked nice, but I am not sure if I can quite do justice to it)
